Hi @Raafat
This seems to be an issue on Oracle's side. Is the data source you connected to the Oracle database data?
I found this link for you: https://stackoverflow.com/questions/68909052/oracle-manageddataaccess-client-oracleexception-0x80004005-connection-request.
If you want to get more detailed information, I suggest you go to the Oracle related platform for help.
Best regards,
Aniya
